The ice making chamber 13 and the temperature changing chamber 14 are arranged between the refrigerating chamber 12 and the freezing chamber 15, and the ice making chamber 13 and the temperature changing chamber 14 are arranged at left and right intervals.

Referring to fig. 3 to 5, in some embodiments, an evaporation chamber 151 is disposed at a back side of the freezing chamber 15, and an evaporator 152 is disposed in the evaporation chamber 151. Evaporator 152 can refrigerate inside evaporation tank 151, thereby forming a large amount of cool air inside evaporation tank 151.

In some embodiments, a freezing air duct 153 is further disposed on the back side of the freezing chamber 15, a plurality of freezing air outlets 154 are disposed on the freezing air duct 153, and the freezing air duct 153 communicates with the freezing chamber 15 through the freezing air outlets 154. Meanwhile, the freezing air duct 153 is communicated with the evaporation chamber 151 through a freezing fan 155. The freezing fan 155 can convey cold air in the evaporation bin 151 into the freezing air duct 153, and supply cold air into the freezing chamber 15 through the freezing air outlet 154, thereby realizing refrigeration in the freezing chamber 15.

The first air duct is communicated with the second air door 144 and the variable temperature air outlet 142, and the second air duct is communicated with the second air door 144 and the first air door 143. Therefore, the cold air in the freezing air duct 153 can sequentially enter the temperature-variable chamber 14 through the first damper 143, the first air duct, and the variable temperature air outlet 142, thereby refrigerating the temperature-variable chamber 14. A third air door (not shown in the figure) can be independently arranged in the first air duct and is used for opening and closing the first air duct, so that the opening or closing of the variable temperature chamber 14 can be independently controlled.

In other embodiments, the variable temperature air duct 141 may not be disposed in the variable temperature chamber 14, and at this time, the cold air in the freezing air duct 153 can directly enter the variable temperature chamber 14 through the first air door 143, so as to cool the variable temperature chamber 14. The cold air in the temperature changing chamber 14 enters the ice making chamber 13 through the second air door 144, so that the ice making chamber 13 is refrigerated.

The driving motor 4 is disposed at one end of the ice making housing 2, and the driving motor 4 is fixed on a sidewall of the ice making chamber 13. The output shaft of the driving motor 4 is connected with one end of the ice making box 2, and then the ice making box 2 can be driven to rotate synchronously. The driving motor 4 is a forward and reverse rotation motor, so that the driving motor 4 can drive the ice making box 2 to rotate forward or reversely, and the ice making and ice removing operations are alternately realized.

The fixed bracket 5 is arranged at the other end of the ice making box 2, and the fixed bracket 5 is fixed on the other side wall of the ice making chamber 13. The other end of the ice making housing 2 is rotatably connected to the fixing bracket 5. Therefore, the driving motor 4 is engaged with the fixing bracket 5 to rotatably fix the ice making housing 2 in the ice making chamber 13 and to be erected above the ice bank 131.

Fig. 9 is a schematic structural view of the ice making housing 2, the first rotating member 6, and the second rotating member 7 of fig. 8. Fig. 10 is an enlarged schematic view of region C in fig. 9. Fig. 11 is an enlarged schematic view of region D in fig. 9.

Fig. 12 is a schematic view of the structure of fig. 7 from another perspective. Fig. 13 is a front view of fig. 7. Fig. 14 is a sectional view taken along line E-E in fig. 13. Fig. 15 is a sectional view taken along line F-F in fig. 13. Fig. 16 is a schematic view of the structure of fig. 15 in another state.

Referring to fig. 7 to 16, the ice making pipe 3 is disposed in the case 1 and extends into the ice making compartment 13. The ice making pipe 3 is used for flowing the refrigerant, and the refrigerant in different states flows in the ice making pipe 3, so that the refrigeration or heating function of the ice making pipe 3 can be realized respectively.

At least a part of the pipeline of the ice making pipe 3, which can be in contact with the ice making housing 2, can be disposed in a spaced area between the first and second

rotating members

6 and 7. Therefore, when the refrigerant in the ice making pipe 3 performs refrigeration, the ice making pipe 3 can directly absorb heat of the ice making box 2 by contacting with the ice making box 2, as shown in fig. 15, direct cooling contact ice making of the ice making box 2 is realized, and the direct cooling contact ice making is matched with air cooling refrigeration in the ice making chamber 13, so that the ice making efficiency of the ice making box 2 is improved.

Meanwhile, the portion of the piping of the ice making pipe 3 disposed between the first and second

rotating members

6 and 7 can be disposed coaxially with the first and second

rotating members

6 and 7. When the driving motor 4 drives the ice making box 2 to rotate through the first rotating member 6, the ice making box 2 can rotate around the part of the pipeline of the ice making pipe 3 by taking the axis of the part of the pipeline of the ice making pipe 3 as a shaft, and the contact state of the ice making box 2 and the ice making pipe 3 is maintained. Therefore, after the ice making in the ice making box 2 is completed, the driving motor 4 can control the ice making box 2 to rotate 180 degrees, so that the ice making cells 21 on the ice making box 2 are arranged downwards, and then the refrigerant in the ice making pipe 3 is used for heating, and the ice making pipe 3 is matched with the ice making box 2 to be contacted, as shown in fig. 16, the heat of the refrigerant is directly transferred to the ice making box 2, so that the ice blocks in the ice making cells 21 can be quickly dropped and stored in the ice storage box 131.

Before the ice making box 2 is turned over and de-iced, the refrigerant in the ice making pipe 3 is used for heating, so that ice at the contact part of the ice making pipe 3 and the ice making box 2 is melted, the ice making box 2 is prevented from being frozen on the ice making pipe 3, and the ice making box 2 is further ensured to be smoothly turned over.

Referring to fig. 7 to 16, in some embodiments, the first rotating element 6 includes a first rotating shaft portion 61 and a first connecting portion 62 that are integrally bent and connected, and the second rotating element 7 includes a second rotating shaft portion 71 and a second connecting portion 72 that are integrally bent and connected. Wherein the first and

second spindle portions

61 and 71 each extend in the axial direction of the output shaft of the drive motor 4 and are arranged coaxially at intervals. One end of the first rotating shaft part 61 is coaxially connected with an output shaft of the driving motor 4, the first connecting part 62 is bent by the other end of the first rotating shaft part 61 and then extends towards the ice making box 2, namely, one end of the first connecting part 62 is bent and then connected with the other end of the first rotating shaft part 61, and the other end of the first connecting part 62 is connected with one end of the ice making box 2. One end of the second rotating shaft part 71 is rotatably connected to the fixing bracket 5, the second connecting part 72 is bent from the other end of the second rotating shaft part 71 and then extends in the direction of the ice making box 2, that is, one end of the second connecting part 72 is bent and then connected to the other end of the second rotating shaft part 71, and the other end of the second connecting part 72 is connected to the other end of the ice making box 2. Therefore, the drive motor 4 can rotate the ice making housing 2 about the axes of the first and second

rotating shaft portions

61 and 71.

Meanwhile, the ice making pipe 3 is coaxially provided in a spaced area of the first and second

rotating shaft portions

61 and 71.
